= 3!

= 3*2*1

= 6

Number of ways 4 can order steak

= 4!

= 4*3*2*1

= 24

Number of ways 1 can order lobster

Find the perimeter and the area of a rectangle with the sides 4 7/20 m and 6 2/3 m.

Simora [160]

9514 1404 393

Answer:

perimeter: 22 1/30 m
area: 29 m²

Step-by-step explanation:

The perimeter is given by the formula ...

P = 2(L+W)

P = 2(4 7/20 +6 2/3) = 2(10 +61/60) = 2(11 1/60)

P = 22 1/30 . . . . meters

The area is given by the formula ...

A = LW

A = (4 7/20)(6 2/3) = (87/20)(20/3) = 87/3 = 29 . . . . square meters

The perimeter is 22 1/30 meters; the area is 29 square meters.

If triangle MNO is similar to triangle PQR, which statement is true about the two triangles?

Neko [114]

The first one. Segment NO is proportional to segment QR, and angles M and P are congruent.

In similar triangles, their angles are congruent but their sides are only proportional. That is why the last three are not true.

Find the value of x. Round the answer to the nearest tenth, if needed.

zepelin [54]

Answer:

Step-by-step explanation:

The diagram is composed of one large right triangle and inside it it's divided into 2 small right triangles. Since these triangles all have the same shape but not the same size, they are similar triangles. Using similar triangles, create a proportion of side lengths. A proportion is an equation with equal ratios from the large triangle to a small. Notice the large triangle has a hypotenuse of 6+7 = 13 and a leg of x. The small triangle has a hypotenuse of x and a leg of 7.

$\frac{hypotenuse}{leg}=\frac{hypotenuse}{leg}$

$\frac{13}{x}=\frac{x}{7}$

To solve for x, cross multiply the numerator with the denominator.

$x*x = 13*7\\x^2 = 91\\x=\sqrt{91} \\x=9.5$
